BASS.L. Near-infrared Data Release 3: A Spectral Atlas and Characterization of AGN
Jarred Gillette, Michael J. Koss, Darshan Kakkad +18
We present an analysis of near-infrared (NIR) emission-line properties, AGN diagnostics, and circumnuclear gas dynamics for 453 hard X-ray selected (14195 keV) AGN from the BAT…
Changing-Look Active Galactic Nuclei in SDSS-V: Host-Galaxy Properties and Black-Hole Scaling Relations
Grisha Zeltyn, Benny Trakhtenbrot, Michael Eracleous +23
Changing-look active galactic nuclei (CL-AGNs) exhibit dramatic spectral variability on unexpectedly short timescales, challenging standard accretion flow models. Despite growing s…
Molecular Gas in Major Mergers Hosting Dual and Single AGN at <10 kpc Nuclear Separations
Makoto A. Johnstone, Ezequiel Treister, Franz E. Bauer +24
We present high-resolution (50100 pc) Atacama Large Millimeter Array (ALMA) observations of CO(2-1) or CO(1-0) emission in seven local ( 0.05)…
BASS LIV. Physical Properties of AGN-Hosting Galaxy Mergers from Multiwavelength SED Fitting
Marco Troncoso, Ezequiel Treister, Alejandra Rojas +17
Galaxy mergers are believed to play an important role in triggering rapid supermassive black hole (SMBH) growth. As merging nuclei approach each other, the physical properties of t…
Optical Emission-Line Properties of eROSITA-selected SDSS-V Galaxies
Nadiia G. Pulatova, Evgenii Rubtsov, Igor V. Chilingarian +21
We present and discuss optical emission line properties obtained from the analysis of Sloan Digital Sky Survey (SDSS) spectra for an X-ray selected sample of 3684 galaxies (0.002 <…
BASS LII: The prevalence of double-peaked broad lines at low accretion rates among hard X-ray selected AGN
Charlotte Ward, Michael J. Koss, Michael Eracleous +18
A fraction of active galactic nuclei (AGN) have double-peaked H, H and Mg II broad lines attributed to emission from rotating gas in the accretion disk. Using optical spectro…
BASS LIII: The Eddington Ratio as the Primary Regulator of the Fraction of X-ray Emission in Active Galactic Nuclei
Kriti Kamal Gupta, Claudio Ricci, Alessia Tortosa +20
Active galactic nuclei (AGN) emit radiation via accretion across the entire energy spectrum. While the standard disk and corona model can somewhat describe this emission, it fails…
BASS XLVIII: [Ne v] λ3427 Emission in Powerful Nearby Active Galactic Nuclei
Tomer Reiss, Benny Trakhtenbrot, Claudio Ricci +14
We investigate the high-ionization, narrow [Ne v] 3427 emission line in a sample of over 340 ultrahard X-ray (14-195 keV) selected Active Galactic Nuclei (AGN) drawn from the BA…
Insights for Early Massive Black Hole Growth from JWST Detection of the [Ne v] λ3427 Emission Line
Benny Trakhtenbrot, Claudio Ricci, Ezequiel Treister +7
We use the narrow [Ne v] 3427 emission line detected in the recently published JWST spectra of two galaxies, at z = 6.9 and 5.6, to study the key properties of the active galact…
BASS. XLIV. Morphological preferences of local hard X-ray selected AGN
Miguel Parra Tello, Franz E. Bauer, Demetra De Cicco +20
We present morphological classifications for the hosts of 1189 hard X-ray selected (14-195 keV) active galactic nuclei (AGNs) from the Swift-BAT 105-month catalog as part of the BA…
ALMA observation of evolving magnetized corona in the radio-quiet changing-state AGN NGC 1566
Arghajit Jana, Claudio Ricci, Sophie M. Venselaar +9
The origin of compact millimeter (mm) continuum emission from radio-quiet AGNs (RQAGNs) is still not fully understood. Changing-state AGNs (CSAGNs) display rapid and strong variabi…
Searching for Compact Obscured Nuclei in Compton Thick AGN
Makoto A. Johnstone, George C. Privon, Loreto Barcos-Munoz +16
Compact Obscured Nuclei (CONs) are heavily obscured infrared cores that have been found in local (ultra)luminous infrared galaxies (U/LIRGs). They show bright emission from vibrati…
BASS XLVII: 22 GHz Radio Atlas of Swift-BAT Selected AGN
Macon Magno, Krista L. Smith, O. Ivy Wong +16
We present the third phase of the largest high-frequency, high-resolution imaging survey of 231 nearby, hard X-ray selected AGN, with a very high detection fraction. T…
Intervening nuclear obscuration changing the X-ray look of the QSO CFHQS J164121+375520
Fabio Vito, William Nielsen Brandt, Andrea Comastri +16
X-ray observations of the optically selected QSO CFHQS J164121+375520 (hereafter J1641) revealed that its flux dropped by a factor from 2018, when it was a bri…
BASS XLV: Quantifying AGN Selection Effects in the Chandra COSMOS-Legacy Survey with BASS
Yarone M. Tokayer, Michael J. Koss, C. Megan Urry +11
Deep extragalactic X-ray surveys, such as the Chandra COSMOS-Legacy field (CCLS), are prone to be biased against active galactic nuclei (AGN) with high column densities due to thei…
